I run the code under matlab 2013a and 2014a； when loaing test image to the GUI, there will be sereval errors showing below:

openpivgui
Index exceeds matrix dimensions.

Error in openpivgui>ReadImageDirectory (line 898)
firstDif = find(handles.files{2}-handles.files{1},1,'first'); % how the
first two files are different?

Error in openpivgui>load_Callback (line 410)
handles = ReadImageDirectory(handles);

Error in gui_mainfcn (line 96)
feval(varargin{:});

Error in openpivgui (line 42)
gui_mainfcn(gui_State, varargin{:});

Error in
@(hObject,eventdata)openpivgui('load_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating uimenu Callback

What's the reason???

I guess it's something related to the fact that the last version is for 2014b and later. Please check this version:

Hallo,
Could somebody help me? I am really a newbie here. So, I have downloaded all of the files of OpenPIV_Spatial_toolbox from http://www.openpiv.net/openpiv-spatial-analysis-toolbox/ . My Matlab is 2018a version. When I want to load the .mat files and .txt files, it only read one file and give me the answer Reference to non-existent field 'x'.
I have 600 files.

However, it worked properly for .vec files. I have searched the solution and mostly stated there is something I have to do with GUI. But I cannot even find GUI files in Spatialbox.

I don't know whether I explain it well, I hope somebody can help me.

Thank you
Regards,
Suwito

Hi,

let's check one thing at a time. Since I do not have an access to Matlab 2018a version, some things we'll need to check on your computer (via teamviewer for instance).

please share your .mat and .txt files so I could test it on another computer/Matlab version.

Thank you for your fast reply,

I tried the test_mat and test_txt files from the downloaded files from http://www.openpiv.net/openpiv-spatial-analysis-toolbox/ but they did not work either. If you may possible to try on Matlab 2017b or 2018a, which both gave me the same problems, I really appreciate it.

Thank you again and looking forward to your help.
Best Regards,
Suwito

Unfortunately I do not have an access to newer Matlab versions. if you share a teamviewer access to your machine, I may try.

let's discuss it over e-mail. send the teamviewer details to openpiv2008@gmail.com the time you're available and your time zone. I'm at GMT+3 and might have some time to check it this evening, e.g. in 6-7 hrs from now. you don't have to be next to the computer if it's open and connected

@wulianlhc

I've got 2018a to test - please:

  1. move the discussion to the issues on openpiv-spatialbox here: https://github.com/OpenPIV/openpiv-spatial-analysis-toolbox/issues

  2. please upload 10 txt files for a test
